Simulate, design, and export production-ready projects — in your browser

Precision Engineering, Zero Setup

SPICE-accurate simulation, mechatronics modeling, and AI-assisted debugging — all in a browser tab your whole team can share.

Multi-Domain Simulation

Run Digital, Analog, SPICE, Microcontroller, and FEA-based simulations with professional-grade accuracy. Newton-Raphson convergence, Bode plots, transient analysis.

RF Yield & FEM Analysis

Run RF system-level yield analysis and Monte-Carlo sweeps, solve FEM on 3D structures, read S-parameters on a Smith chart, and drive parametric optimization to shorten the development cycle.

Mechatronics & Robotics

Simulate real-world mechatronic systems — robotics, aeronautics, motor control — with physics-accurate models and real-time feedback.

VirtuBuild Space

Full workspace with ESP32, RP2040, Arduino Uno support. Drag-and-drop schematic capture, real-time node voltage analysis, and component-level debugging.

AI-Powered Assistance

Intelligent debugging, design suggestions, and automated test generation powered by advanced AI models that understand your circuit topology.

From RF Analysis to Fabrication

Three capability areas that carry one design from a first prompt through RF simulation to the Gerber files, STL models, and BOM your fab house needs.

RF Simulation & Optimization

Run RF system-level simulation with yield analysis and Monte-Carlo sweeps, solve RF FEM on 3D structures like antennas and filters, and read S-parameters on every frequency-domain graph type you need.

• Run system-level RF simulation with yield analysis and Monte-Carlo sweeps across component tolerances.
• Solve RF FEM on 3D structures and extract S-parameters from each port.
• Plot frequency-domain results on a Smith chart, magnitude sweep, or phase graph.
• Sweep design parameters through parametric optimization to shorten the product development cycle.

Prompt-Driven 3D Design

Describe an antenna or enclosure in a prompt and get a first simulatable 3D structure back. You review the geometry, edit dimensions, then run RF FEM on it and read the Smith chart.

• Write a prompt describing an antenna; the platform drafts a 3D structure.
• Engineers review, edit, and validate the generated geometry before any simulation runs.
• Run RF FEM simulation on the edited 3D structure with no re-drawing.
• Read the resulting S-parameters on a Smith chart in the same workspace.

Layout, 2D, and 3D Views

One design, three views: switch between the layout, 2D, and 3D views with no re-drawing and no re-entry. All three read the same design data, and the layout view exports Gerber files, STL models, and a BOM.

• Switch between layout, 2D, and 3D views of the same design data instantly.
• Edit once: every view updates, with no re-drawing and no re-entry of the design.
• Export Gerber files, STL models, and a BOM straight from the layout view.
• Hand the exported files to a fab house, contract manufacturer, or 3D printer.

Built for Every Engineering Context

From weekend prototyping to enterprise R&D, NevilLabs fits how you already work.

Hobbyist Prototyping

Design and simulate personal projects — from custom PCBs to robot controllers — before ordering physical components. Validate before you build.

Pre-Fabrication Validation

Sweep component tolerances and solve FEM on a design before committing to a fabrication run. Catch the failure in simulation, not in the first batch of boards.

Enterprise R&D

Rapid prototyping and design validation for engineering teams. Share projects, review simulations, and iterate faster than physical prototyping allows.

Team Upskilling

Browser-based training platform for onboarding engineers. Interactive simulations replace static documentation. Measurable skill development.
